Microchampsa is an extinct genus of protosuchian crocodylomorph that existed during the Early Jurassic. Fossils have been found from stratum 6 of the Dahuangtian locality, an outcrop of the Lower Red Beds of the Lufeng Formation in Yunnan, China. Parts of the postcranial skeleton, such as the dorsal osteoderms, vertebrae, ribs, and bones of the manus, are known. The dorsal osteoderms of the lumbar region are fused to double headed ribs. All osteoderms are rectangular and overlap each other.
